  Error Message
  WS535: Maximum number &1 of documents reached
  
  Cause
  This error occurs when the number of documents opened simultaneously in a SAP session exceeds the system-defined limit. SAP GUI allows users to open multiple documents (sessions) at the same time, but there is a maximum number set to prevent excessive resource consumption.
  
  The placeholder &1 in the message indicates the maximum number of allowed sessions/documents.
  When a user tries to open more sessions/documents than this limit, the system throws this error.
  
  
  Explanation
  
  SAP GUI supports multiple sessions per user (usually up to 6 by default).
  Each session corresponds to a separate window or document.
  The system parameter controlling this limit is rdisp/max_alt_modes.
  If a user tries to open more sessions than allowed by rdisp/max_alt_modes, the error WS535 is triggered.
  
  
  Solution
  
  
  Close Unused Sessions:
  
  The immediate solution is to close some of the open SAP sessions/documents to free up slots.
  Check your open SAP windows and close those not in use.
  
  
  
  Increase the Maximum Number of Sessions (if necessary and authorized):
  
  If business requirements demand more sessions, the system administrator can increase the limit.
  This is done by changing the parameter rdisp/max_alt_modes in the SAP system profile.
  Steps:
  
  Go to transaction RZ10 (Edit Profiles).
  Select the instance profile.
  Add or modify the parameter rdisp/max_alt_modes to a higher value (e.g., from 6 to 10).
  Save and activate the profile.
  Restart the SAP instance for the change to take effect.
  
  
  
  
  
  Educate Users:
  
  Inform users about the session limit and encourage them to close sessions when not needed.
